G193 and G194 pressure switches are not fitted after build date – August 2004.Hydraulic Control The shifting elements are controlled by the valve body which are activated by the solenoids. The solenoids are in turn activated by the TCM (J217) In addition to the shifting elements the valve body controls the TCC and the mainline pressure, control pressure, converter pressure and lubrication pressure. When inserting the torque converter into the housing, do so vertically (input shaft facing up) to avoid damage to the drivers. Oil Pump Design The oil pump is designed without a crescent. This makes it very unstable and easily broken. Lock Lock‐up up is in operation in 2 is in operation in 2nd gear and above gear and above.Lock‐up is engaged if ATF temperature exceeds 130 C.The Lock‐up clutch engages without slip in “S” mode.Minimal slip to improve fuel consumption Mi i l li i f l i.This greatly expands the range in which the lock‐up can remain locked by reducing vibration. The torque converter lock up Th l k clutch has integrated torsion dampers.

It is arranged in parallel with the B2 h lFi h i l hifti l t It i di ll l ith th B2 brake. t The clutches achieve a control behaviour that is independent of engine speed through their dynamic pressure equalization. The K1,K2, and K3 clutches pass the engine torque into the planetary gear. The B1 and B2 brakes along with the i t i t th l t Th B1 d B2 b k l ith th Freewheel F support the engine torque at the transmission housing. All clutches and brakes are indirectly controlled by the electrical pressure control valves. The K2 clutch and the B2 brake along with the freewheel F, are located on the d bl l t double planetary gear set. The K1 and K3 clutches along with the B1 brake are located on the simple planetary gear set. The number of planetary gears depends on the transmission’s l t t Th b f l t d d th t i i ’ torque transfer. Shifting Elements The planetary gear set is a Lepelletier design. The engine torque first drives a simple planetary gear set. From the simple planetary gear set, it is transferred to a i l l t t F th i l l t t it i t f dt Ravigneaux double planetary gear set.

Both the front wheel drive versions and the rear wheel drive 09D use the arrangement They both combine a simple planetary gear set Lepelletier arrangement. They both combine a simple planetary gear set with a Ravigneaux arrangement. The transmission sets new standards for dynamics and efficiency as a y y conventional front wheel drive unit.
